EINSTEIN THEORY CONFIRMED

A PHENOMENAL AGREEMENT LICK OBSERVATORY'S RESULTS. (VNITI* PRESS ASSOCIATION.—COFIRIQKT.) (ABITRALIAN • NEW ZEALAND OAILI ASSOCIATION.) (Received 13th April, 9 a.m.) NEW YORK, 12th April. It is reported from Mount Hamilton, California, that calculations made from the eclipse photographs taken by the Lick Observatory Expedition at Wallal bear out the Einstein Theory. Two photographs of the stars surrounding the sun during the eclipse were taken, and these were compared with photographs of the same stars taken at Tahiti three months earlier. The Director of the Lick Observatory, Dr. Campbell, and Dr. Trumpler I have announced that the agreement between Einstein's prediction (as to the displacement of the stars' rays outwardj with reference to the centre of the sun) and the extremely exact measurements ijjade by these two scientists' of the photographic plates is absolutely phenomenal. Einstein predicted that the displacement of a star's ra^s while passing through the sun's gravitational field would be 1.75 seconds of arc. The scientists, after subjecting as many as 84 stars appearing on the plates to rigorous mathematical treatment, found the displacement to average 1.74 seconds of arc. Dr. Campbell stated that "the agreement of our observed value with the predicted value is so satisfactory that the Lick Observatory; does not plan to repeat the Einstein test at the total solar .eclipse, due to occur in California and Mexico on 10th September."
